Goltsman G. Quantum-photonic integrated circuits. In: Proc. IWQO.; 2019. p. 22–3.
Abstract: We show the design, a history of development as well as the most successful and promising approaches for QPICs realization based on hybrid nanophotonic-superconducting devices, where one of the key elements of such a circuit is a waveguide integrated superconducting single-photon detector (WSSPD). The potential of integration with fluorescent molecules is discussed also.

Abstract: We consider practical aspects of using standard fiber-optic elements and superconducting nanowire single-photon detectors for the development of a practical quantum receiver based on the Kennedy scheme. Our receiver allows to discriminate two phase-modulated coherent states of light at a wavelength of 1.5 microns in continuous mode with bit rate 200 Kbit/s and error rate about two times below the standard quantum limit.

Abstract: Разработаны и исследованы сверхпроводниковые однофотонные детекторы, способные к разрешению до 3-х фотонов в коротком импульсе излучения и имеющие квантовую эффективность детектирования одиночных фотонов ~60% на длине волны lambda=1.55 мкм. Проведенная модернизация технологии изготовления детекторов, позволила получить приемные устройства с мультифотонной квантовой эффективностью, приближающейся к расчетным значениям.

Abstract: We demonstrate superconducting niobium nitride nanowires folded on top of lithium niobate substrate. We report of 6% system detection efficiency at 20 s−1 dark count rate at telecommunication wavelength (1550 nm). Our results shown great potential for the use of NbN nanowires in the field of linear and nonlinear integrated quantum photonics.

Abstract: We showcase an optical random sampling scope that exploits single photon counting and apply it to characterize optical transceivers. We study single photon detectors with a jitter down to 40 ps. The method can be extended beyond 100 GHz.
